A reappraisal of rat motor cortex organization by intracortical microstimulation
Brain Research, 1985The organization of the motor cortex was reinvestigated with intracortical microstimulation, in light-anaesthetized (ketamine) rats. A posterolateral (PL) vibrissae area was found in addition to the rostral one, and blinks of the contralateral eyelids were elicited from a part of this PL area.

Ultrasonically-assisted intracortical microstimulation of the rat
The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005High frequency tone bursts of ultrasound are capable of increasing the sensitivity of rat motor cortex to electrical stimulation. In this study, 11.75 MHz ultrasound pre-stimuli were delivered to the forelimb motor region of the rat cortex followed by an electrical pulse train to assess changes in cortical activation. The temporal peak intensity of the

Intracortical microstimulation of human somatosensory cortex
Science Translational Medicine, 2016Tactile percepts were consistently elicited in the hand of a person with cervical spinal cord injury using intracortical microstimulation of the somatosensory cortex.

Intracortical microstimulation of neurons in the visual cortex of the cat
Electroencephalography and Clinical Neurophysiology, 1981The response of visual cortex neurons to local intracortical microstimulation was measured in the anesthetized cat. When the recording microelectrode was very close (about 20 micrometers) to the tip of the stimulating electrode, threshold currents as low as 10 micro A were capable of firing neurons.

Intracortical Microstimulation of Bilateral Frontal Eye Field
Journal of Neurophysiology, 1998Fujii, Naotaka, Hajime Mushiake, and Jun Tanji. Intracortical microstimulation of bilateral frontal eye field. J. Neurophysiol. 79: 2240–2244, 1998. We trained two monkeys to perform a fixation task. Intracortical microstimulation (ICMS) was applied to the monkey frontal eye field (FEF) while monkeys were fixating on one of five fixation LEDs.

Excitation of visual cortex neurons by local intracortical microstimulation
Experimental Neurology, 1983The threshold current required for the excitation of visual cortex neurons in the vicinity (approximately 1 mm) of an intracortical stimulating electrode was measured as a function of the stimulus pulse duration in the anesthetized cat. For cortical neurons with latencies of activation from 0.4 to 3.4 ms and for stimulus pulse durations from 0.02 to 0 ...

A Miniaturized System for Spike-Triggered Intracortical Microstimulation in an Ambulatory Rat
IEEE Transactions on Biomedical Engineering, 2011This paper reports on a miniaturized system for spike-triggered intracortical microstimulation (ICMS) in an ambulatory rat. The head-mounted microdevice comprises a previously developed application-specific integrated circuit fabricated in 0.35-μm two-poly four-metal complementary metal-oxide-semiconductor technology, which is assembled and packaged on

High‐voltage compliant microelectrode array drivers for intracortical microstimulation
International Journal of Circuit Theory and Applications, 2015SummaryWe present in this paper two low‐power high‐impedance microelectrode array drivers (MEDs) dedicated for visual intracortical microstimulation. These output stages of a new microstimulator are highly configurable and able to deliver higher compliance voltage (20 V for anodic and cathodic phases) across microelectrode‐tissue interface impedance ...
